Looking at the manual, it appears to be coming through the seam between the cylinder housing where the safety valve is located and the lift cover. I think this may be the same thing I just dealt with 6 months ago but not "spraying" this time as it was then.

That ram cylinder safety valve under the accessory plate/down in the big hole is shown in the I&T manual to dump into the exhaust tube along with the back pressure via unloader valve, BUT those dump paths, unlike all the other connections between the ram/valve body casting & lift cover, have no sealing such as O-ring or gasket, so it seems free to leak to me & I guess it wouldn't matter as it dumps back into bottom of hyd cavity any way. I might expect your "leak" to be from back pressure/unloader when in unloading )hold or lower, but not lift) or from ram cyl safety during attempted lift if it is stuck open.

Jesse, you may recall I just replaced the cylinder safety valve last Fall. Should the safety valve even open if there is not a problem causing excessive pressure? The source looks to be from the same spot as last fall though it was shooting out probably because I had a bush hog attached when trying to lift.
